Hello All,

I added a new nic card so now I have two one on the MB and on in a pcie slot. How can i tell if they are set up correctly? After I added the card I went to settings network interface rules and switched the MAC addresses so that the new nic should be eth0 and the old one eth1.

When i rebooted the server it looks like I am at 2.5Gb speed but it looks like it bonded the two NICs. Is this the way it should be run? It also looks like eth0 is down? But shouldn't it be the other way around?

Please post the diagnostics.

Sorry here are the diagnostics.

This is not the correct way; the new NIC is still eth1. Change that in Settings > Network Settings > Interface Rules; a reboot is required for the changes to take effect, though since you messed with the network-rules.cfg files, it may be best to delete it and let Unraid recreate it first.

I am not sure I follow you. I went to settings>network settings>interface rules and switched the Mac addresses when i installed the second NIC before i rebooted and moved the ethernet cable to the new NIC. Was that not correct?

I understood you manually changed the MAC address on the network-rules.cfg file, if you used the GUI the change was not done correctly or it didn't take; the new NIC is still eth1, try doing it again, reboot, then post new diags.

I only used the gui. I did not make any changes to the config file. What is the correct process for adding a new NIC? I understood it to be install chance MAC addresses in gui then reboot and plug Ethernet cable into new nic.

Ok so i have gone into the GUI and changed the MAC addresses. Then i rebooted the system and it now states this.

I have attached the latest diag file as well. Is this what I want to see?

That shows eth0 is now the 2.5Gbps NIC. However you may want to disable the bonding as it is unlikely to be serving any practical pupose.

Will it hurt to leave it enabled? Is it needed for tailscale at all?

If you leave the bond enabled, it can use eth1, if you prefer to disable it, then you need eth0 to be the main one.

so right now it is using the new NIC as eth0 correct and eth1 is disabled. So disabling bonding would be fine. OR if I leave it on and eth0 fails will it roll over to eth1 if i have it connect to my routher?

This will also work, but IIRC bonding two different speed NICs limits the speed to the slowest one (if both are connected).

Ok so how do i disable bonding? Is it as simple as changing this to no?

This field is a dropdown - click the arrow on the right and set it to "no".
